Vintage Brawn™

The Premium Protein Blend

Vintage Brawn™

Vintage Brawn™ is a blend of three protein sources: eggs, milk (casein + whey) and beef. It is far superior than any single-source protein like whey. Why? Because as a blend, it provides a complete amino acid profile and a powerful muscle-building effect that not only kicks in fast, but lasts for hours.

Vintage Brawn™ - $49.99

Way Better Than Whey

Vintage Brawn™ is the first protein blend to combine the isolate forms of the three most-prized protein sources Golden Era athletes relied on to build their lean muscle mass and speed recovery – a protein drink that’s richer and tastier than any naturally flavored whey protein.

Made from US farm-raised eggs, New Zealand hormone-free milk, and USDA beef. It has zero artificial substances, zero synthetic additives, zero preservatives, and no added aminos.

+ What Sets It Apart

These days, chances are if you’re using a protein powder, it’s whey protein. Whey has become the protein choice for everyone, from kids to grandparents. A byproduct of cheese production, whey is particularly prized for its absorption speed. It’s a good protein, but it’s not the most effective way to build muscle, nor to reduce muscle loss. Yet, we’ve been told over and over again that whey is the only protein we need to achieve our goals. 

For us at Old School Labs™, that just doesn’t make sense!

Golden Era athletes relied on eggs, milk, and beef – the Big Three – to build high quality muscle. Today, science is catching up with what these athletes knew all along: that the combined proteins of the Big Three surpass the muscle-building and muscle-preserving properties of whey, or any single source. Why? Because together they deliver a synergistic muscle-building effect that’s more powerful – it kicks in fast and lasts for hours.

Vintage Brawn™ is the first supplement to successfully combine the highest quality isolates of these three prized proteins. Which means you get all the muscle-building power without the extra fat, sugar, or cholesterol – in an incredibly tasty protein powder.

The Ingredients

Not all supplement ingredients that go by the same name are created to be equally as effective. Just as there are different qualities of the same cut of meat, there are different qualities for the same supplement ingredients.

+ What These Ingredients Do

Egg White Protein

Eggs have long been considered a perfect source of bodybuilding protein. They have a full complement of essential amino acids and they are easy to digest. However, they also contain fat and cholesterol, which is why we use only egg white protein in Vintage Brawn™ – sourced from eggs produced in the USA.

Milk Protein Isolate

Milk protein isolate (MPI) may be one of the most overlooked protein sources in sports nutrition. The two major proteins in milk are casein and whey. While whey tends to be absorbed quickly, casein has a “sustained-release” profile. MPI extracts these two complementary proteins from milk, leaving behind virtually all of the fat, sugar (lactose), and other nutritional “baggage".  

Beef Protein Isolate

We use a beef protein isolate made from fresh beef using a USDA-approved process. It contains high levels of conditionally essential amino acids and is easy to digest.

Dutch Cocoa Powder¹

Gives Vintage Brawn™ its signature rich and deep chocolate flavor. It has a more intense and smoother taste than regular cocoa.

Natural Flavors

Countless iterations of taste-testing allowed us to arrive at a flavor that is not only natural, but tastes great and mixes easily. 

Vegetable-Based Antifoam²

Helps reduce the formation of foam. It is made of Silica, Propylene Glycol, Mono and Diglycerides.  

Organic Stevia Leaf Extract

Stevia is a natural sweetener which is extracted from the Stevia rebaudiana plant. It has no calories.  

Sea Salt

Also known as Sodium Chloride, helps bring out the flavors. 

Monk Fruit Extract

A natural, zero-calorie sweetener.  

Xylitol Crystalline³

Also a natural sweetener.

Ask Us Anything

1. I’m trying to gain muscle, so what is the best way to use Vintage Brawn™?
Have a Vintage Brawn protein shake right after your workout. You can also use Vintage Brawn as a meal replacement any other time of day, e.g. first thing in the morning (breakfast), as a mid-afternoon snack, or before bed.
2. Can I use Vintage Brawn™ on a fat-loss or cutting diet?
Absolutely. Taking it after workouts will help you preserve lean muscle and boost your metabolism. Using it as a meal replacement – especially to replace a higher-calorie meal – can help you lose fat faster. Vintage Brawn can also help you regulate your appetite: Protein tends to be satiating. Plus, the delicious taste of Vintage Brawn™ helps satisfy cravings for sweets.
3. Should I have a protein shake after cardio?
Having Vintage Brawn™ after cardio is a great way to enhance recovery. Plus, because it’s high in protein but low in carbs, it won’t cause your fat-burning metabolism to slow down, unlike what happens if you eat a meal high in carbs (especially high-GI carbs).
4. Can I use Vintage Brawn™ in recipes?
Yes. There are all kinds of protein powder recipes online. Protein puddings, cupcakes, pancakes, and so forth. Vintage Brawn™ can be used in many different recipes besides shakes and smoothies.
5. Does it have any beef or egg aftertaste?
We can happily confirm that there is absolutely NO beef or egg taste or aftertaste (nor milk for that matter). The flavor is delicious rich chocolate, made with natural Dutch cocoa. Vintage Brawn™ is possibly the best-tasting naturally flavored and naturally sweetened protein powder on the market today.
5. Is Vintage Brawn™ lactose free?
Vintage Brawn™ shouldn’t cause any negative side-effects for individuals who are lactose-intolerant, as their sensitivity stems from the inability to properly breakdown the SUGARS (lactose) in milk. Vintage Brawn™ contains milk protein isolate (MPI) – meaning the lactose and fat have been extracted and removed – to leave behind ONLY the two milk proteins casein and whey.
